Melting ice sheets could raise sea levels high enough to flood coastal areas around the globe by the end of the century, according to scientists gathering in Denmark today for a three-day climate-change conference. The phenomenon could affect regions including Florida, the Netherlands, Bangladesh, and the Maldives, the British Guardian newspaper reports.
The meeting, which brings 2,000 scientists to Copenhagen, is a run-up to December's international climate talks, where officials are set to draft a successor to the Kyoto treaty to limit carbon dioxide emissions. Experts will also update the work of the Intergovernmental Panel on Climate Change (IPCC), which released its findings on global warming two years ago. Some of that new information centers on the effects of glacier melts in Greenland and Antarctica.

Three months after NASA dropped 90 rubber ducks into holes in Greenland’s fastest-moving glacier to track the melting of Arctic ice, there’s no sign of the toys.
The duckies were deposited into moulins (tubular holes) in the Jakobshavn Glacier in mid-September by Alberto Behar, a robotics expert at NASA’s Jet Propulsion Laboratory in Pasadena, Calif. The idea was that the ducks would float along the same channels that melt waters do, and wherever they emerged would reveal the path of the disappearing ice.
The ducks have Behar’s e-mail address stamped on them, along with the word "reward" in three languages, including Inuit. NASA is offering $100 to the first person who locates a duck, London's Guardian newspaper notes.
